present themselves anew and with undiminished interest* to every man born into the world."    An essential preliminary to the solution of these problems is a study of the biology of the Anthropoid Apes—the Gibbons, Orang-Qutan, Chimpanzee and Gorilla,
Anatomy and Physiology.—The first requirement is an examination of the external characters and internal structure of the Apes, and this mubt be carried out with the thoroughness and minuteness which are employed in the study of human anatomy. The large series of data so obtained must then be submitted to a physiological analysis, in order that the significance of each group of characters can be understood. When that has been done the following conclusions can be made: The Anthropoid Apes resemble Man in a general way in form and structure, but they differ from him in several respects. Some of the differences are associated with diet and habits, particularly locomotion; others are dependent on the size and complexity of the brain; and others again are the outcome of different developmental processes.
Bio-Chemistry and Pathology. — Certain biochemical reactions, which are described on p. 255, have shown that there is a true blood-relationship between the Apes and Man; and pathological investigations have proved that they are liable to similar diseases* both contracted naturally and induced experimentally. So it is evident that their constitutions have much in common.
Pgyehology,—The psychologist will find much scope for his highly philosophical work in a study of the mentality of the Apes and Man, for they exhibit considerable differences in hierh ftmntinn
